Description
CROSS REFERENCE TO RELATED APPLICATIONS
[0001] This application is a continuation of U.S. patent
application Ser. No. 14/570,216, filed on Dec. 15, 2014, which
claims the benefit of Japanese Priority Patent Application JP
2013-267723 filed on Dec. 25, 2013, the entire contents of which
are incorporated herein by reference.
BACKGROUND
[0002] The present disclosure relates to a display device such as a
television set.
[0003] For display devices typified by a liquid crystal display
device, an organic EL display device, and an electrophoretic
display device, and so on, there has been desired weight reduction
and enhanced designability. A general display device has a
configuration in which a display panel is accommodated in a casing
(for example, Japanese Unexamined Patent Application Publication
No. 2008-304630). The casing includes, for example, a first frame,
a second frame, and a back surface cover, and so on. The first
frame covers a part (an outer edge) of a front surface of the
display panel. The second frame supports the display panel from
behind a back surface.
SUMMARY
[0004] In recent years, progress in technology of display panels or
electronic components allows thinning of display devices, as well
as improvement in designability of appearance. However, since
display devices configured as described above have limitations in
weight reduction and enhancement of designability, there has been
desired further improvement.
[0005] It is desirable to provide a display device that makes it
possible to reduce weight and enhance designability.
[0006] According to an embodiment of the present technology, there
is provided a display device including: a display panel that
includes a display layer on at least a first substrate; and a
sealing resin layer that is provided on a peripheral edge of the
display panel, wherein a surface of the sealing resin layer and a
surface of the display panel include a same plane.
[0007] In the display device according to the above-described
embodiment of the present technology, since the peripheral edge of
the display panel is sealed by the sealing resin layer that
includes the same plane as the surface of the display panel, a
configuration of structural members is simplified. For example, it
becomes possible to eliminate a front surface member.
[0008] According to the display device in the above-described
embodiment of the present technology, the sealing resin layer is
provided on the peripheral edge of the display panel, and the
sealing resin layer includes the same plane as the surface of the
display panel. This leads to a simplified configuration of
structural members, making it possible to reduce weight and enhance
designability. It is to be noted that some effects described here
are not necessarily limitative, and any of other effects described
herein may be achieved.
[0009] It is to be understood that both the foregoing general
description and the following detailed description are exemplary,
and are intended to provide further explanation of the technology
as claimed.

DETAILED DESCRIPTION
[0018] Hereinbelow, some embodiments of the present disclosure will
be described in detail in the following order, with reference to
the accompanying drawings.
[0019] 1. Embodiment (an example in which a polarization plate on a
front surface side and a sealing resin layer include a same plane)
[0020] 1-1. Configuration of Main Part [0021] 1-2. Overall
Configuration
[0022] 2. Modification Example (an example in which the front side
polarization plate is extended to an end surface of the sealing
resin layer)
[0023] 3. Application Example
1. Embodiment
1-1. Configuration of a Main Part
[0024] FIG. 1 illustrates a cross-sectional configuration of a main
part (a display panel 10A and its periphery) of a display device (a
display device 1) according to one embodiment of the present
disclosure. In the display device 1, a sealing resin layer 20 is
provided on a peripheral edge of the display panel 10A. A surface
of the sealing resin layer 20 and a surface of the display panel
10A (specifically, a polarization plate 15A) include a same plane.
To the surfaces of the display panel 10A and the sealing resin
layer 20, a lamination film 21 may be attached.
[0025] The display panel 10A is adapted to display images such as
moving images or still images or the like, and may include, for
example, a cell 11 that may include a display layer (here, a liquid
crystal layer 13) between two substrates, i.e. a TFT substrate 12
(a first substrate) and a color filter (CF) substrate 14 (a second
substrate). The cell 11 may include a polarization plate 15A (on a
front surface side) and a polarization plate 15B (on a back surface
side) that are adapted to allow polarized light in a specific
direction to pass through. The polarization plates 15A and 15B may
be provided on opposite surfaces (a front surface (a display
surface) and a back surface) to the liquid crystal layer 13 of the
TFT substrate 12 and the CF substrate 14, respectively.
[0026] The TFT substrate 12 may have a configuration in which, for
example, a plurality of pixel electrodes (not illustrated) are
arranged in a matrix on a glass substrate. The TFT substrate 12 may
be provided with TFT (thin film transistor) devices, and gate lines
and source lines (neither illustrated). The TFT devices are
configured to drive the plurality of pixel electrodes. The gate
lines and the source lines are connected to the TFT devices. The
pixel electrodes may be configured of a transparent conductive
material such as ITO (indium tin oxide), and may be formed for each
subpixel (not illustrated) on the glass substrate.
[0027] The CF substrate 14 may include, on a glass substrate, a
color filter (not illustarted) together with an opposite electrode
(not illustrated). The color filter may include, for example,
filters of red (R), green (G), and blue (B) in stripe shapes. The
opposite electrode may be provided on a substantially entire
surface of an effective display region S2 over the color filter
(refer to FIG. 2). The opposite electrode may be configured of a
transparent conductive material such as ITO, similarly to the
above-mentioned pixel electrode. It is to be noted that, although
not illustrated, a spacer may be provided between the opposite
electrode and the pixel electrode on the TFT substrate 12 side in
order to maintain a gap between both substrates.
[0028] The liquid crystal layer 13 may include, for example, in a
case of a liquid crystal panel of vertical alignment type, liquid
crystal molecules and a polymer structure. The liquid crystal
molecules have negative dielectric anisotropy. The polymer
structure is adapted to hold the liquid crystal molecules in the
vicinity of a boundary with an orientation film (not illustrated).
The liquid crystal molecule has a property that a dielectric
constant in a long axis direction is larger than that in a short
axis direction. This property allows the liquid crystal molecules
to be aligned with long axes of the liquid crystal molecules
vertical to the substrate when a drive voltage is OFF, and with the
long axes of the liquid crystal molecules parallel to the substrate
when the drive voltage becomes ON. Thus, an image is displayed on
the liquid crystal panel. It is to be noted that the liquid crystal
layer 13 may be sealed by a sealing section (not illustrated) that
is provided on a periphery of the liquid crystal layer 13 between
the TFT substrate 12 and the CF substrate 14.
[0029] The sealing resin layer 20 is provided, as mentioned above,
on the peripheral edge of the display panel 10A. This allows a
level difference in an end surface of the cell 11 to be planarized.
The level difference is caused by a combination of structural
members having different sizes from each other (that is, the
substrates 12 and 14, and the polarization plates 15A and 15B).
Further, in the present embodiment, the surface of the sealing
resin layer 20 and the surface of the planarization plate 15A on
the display surface side form a same plane.
[0030] For the sealing resin layer 20, for example, general resin
materials may be used. In particular, a photocurable resin may be
preferably used. Specific examples may include an acrylic resin, an
epoxy resin, and a silicone resin. Among them, one that has low
shrinkage after curing may be preferable, and in particular, a
silicone resin may be suitable. The sealing resin layer 20 may be
colored; for example, coloring in black makes it possible to reduce
light leakage from a side surface of the liquid crystal layer 13 or
the like. Examples of methods of coloring the sealing resin layer
20 may include adding a colorant, or using a resin material that is
configured to change in color (to be colored) by light irradiation
at the time of curing. For the colorant, one that is capable of
maintaining a transmittance of a sealing resin material may be
preferable; specific examples may include carbon black, or a
metal-containing dye, or the like.
[0031] It is to be noted that the sealing resin layer 20 is not
limited to a case that the sealing resin layer 20 is provided on
the entire peripheral edge of the display panel 10A. For example,
the sealing resin layer 20 may be provided along only one side of
the display panel 10 in a rectangular shape as illustrated FIG. 2.
Alternatively, the sealing resin layer 20 may be provided along
four sides intermittently. The sealing resin layer 20 may be
provided as necessary.
1-2. Overall Configuration
[0032] FIG. 2 is a perspective view illustrating, in an exploded
manner, an overall configuration of the display device 1. FIG. 3
illustrates a cross-sectional configuration of the display device
1. The display device 1 is a display device used as, for example, a
television set. In the display device 1, optical members other than
the display panel 10 may be accommodated in a casing 30. The
optical members may include, for example, an optical sheet 16, a
light guide plate 17 including a light source 17A and so on, a
reflection plate 18, and a backlight unit 19. The casing 30
includes a back surface member 31 and a support member 32. The
display panel 10 may be configured of the above-described display
panel 10A or a display panel 10B that will be described later, and
may be attached to the support member 32 by an adhesion member 22.
On one end surface of the light guide plate 17, a plurality of LEDs
may be provided as a light source 17A. Thus, light emitted from the
light source 17A is allowed to pass through the light guide plate
17, to illuminate the display panel 10, and to be extracted as
display light on the display surface side.
[0033] The optical sheet 16 is a sheet to obtain various optical
effects on light that is produced from the light source 17A and
illuminates the display panel 10 through the light guide plate 17.
The optical sheet 16 may be a single sheet or stacked sheets that
have the following functions: for example, a function of separating
display light that is incident on the display panel 10 from the
light source 17A through the light guide plate 17 into the incident
light and a polarized light component orthogonal to the incident
light; a function of compensating a phase difference in light waves
to widen a viewing angle or to prevent coloring; or a function of
diffusing display light.
[0034] The light guide plate 17 is adapted to allow light incident
from the light source 17A to propagate and to be guided toward the
display panel 10, and may have a shape of, for example, a
rectangular plate. Examples of materials of the light guide plate
17 may include a material having a high transmittance, for example,
glass. However, the light guide plate 17 may be configured of other
materials as long as the materials are capable of propagating light
from the light source 17A. For example, the light guide plate 17
may be configured of a light scattering material in which light
scattering particulates are distributed, or a light diffusing
material. Specific examples may include an acrylic resin,
polymethyl methacrylate (PMMA), polycarbonate (PC) and cyclic
polyolefin (COP), and so on. A shape or a size, a refractive index,
a density, and density distribution, and so on of the light guide
plate 17 may be arbitrarily adjusted in order to obtain desired
characteristics.
[0035] As the light source 17A, for example, in addition to a white
LED (light emitting diode), LEDs that produce red, blue, and green,
and so on may be adopted. Moreover, in addition to point light
sources such as LEDs, linear light sources such as a fluorescent
lamp may be used. Here, the light source 17A is provided on one end
surface (a bottom surface) of the light guide plate 17 as
illustrated in FIG. 2. However, this is not limitative, and the
light source 17A may be provided, for example, along four sides of
the light guide plate 17.
[0036] The casing 30 may have, for example, a substantially
rectangular parallelpiped shape, and may include two opposite
surfaces (a front surface (a support section that supports the
display panel 10) and a back surface) and side surfaces between
these two surfaces. Specifically, the casing 30 is configured of a
back surface plate (the back surface member 31) and a front surface
plate (the support member 32). The back surface plate (the back
surface member 31) is configured to accommodate the above-mentioned
backlight unit 19 and so on. The support section (the support
member 32) is a frame body having an opening in a surface facing
the back surface member, and includes a support section (a frame
section 32A) that is configured to support the display panel 10. It
is to be noted that the back surface member 31 and the support
member 32 are fastened to each other with a screw 33.
[0037] The back surface member 31 is adapted to accommodate, as
mentioned above, the backlight unit 19 and so on, exclusive of the
display panel 10, to cover back surfaces and side surfaces of them.
As a material of the back surface member 31, for example, a metal
having high thermal conductivity, specifically aluminum (Al) may be
used. In addition, iron (Fe), or polycarbonate (PC) or a plastic
added with an ABS resin, or the like may be used.
[0038] The support member 32 is adapted to adhere to and fix the
display panel 10 as mentioned above, and to seal the backlight unit
19 and so on that are accommodated in the back surface member 31.
As a material of the support member 32, similarly to the back
surface member 31, for example, a metal having high thermal
conductivity, specifically aluminum (Al) may be used. In addition,
Fe and so on may be also used.
[0039] It is to be noted that, in the present embodiment, the back
surface member 31 and the support member 32 are fastened with the
screw 33, but this is not limitative. For example, an adhesive may
be used for adhesion. In this case, in order to increase adhesion
strength, it is preferable that the back surface member 31 and the
support member 32 be configured of a same material. Further, the
use of a metal material may be preferable, for example, in order to
shield electromagnetic waves that are generated from various
circuits or electronic components provided in the display device 1.
This contributes to reduction in unnecessary radiation that is
produced from various circuits or electronic components provided in
the casing 30.
[0040] The adhesion member 22 is adapted to allow the display panel
10 to be attached to the casing 30 (specifically, the frame section
32A of the support member 32). Examples of the adhesion member 22
may include an adhesive having sufficient adhesion ability and
elasticity, specifically, an acrylic resin, an urethane resin, an
epoxy resin, a vinyl chloride resin, a modified silicone resin, and
so on.
[0041] The display device 1 may be completed as follows. As
illustrated in FIG. 2, the optical sheet 16, the light guide plate
17, the reflection plate 18, and the backlight unit 19, and so on
are accommodated in the casing 30. Then, for example, the casing 30
is mounted on a stand 40 that is provided with driver substrates of
the light source 17A and speaker units and so on. Examples of the
stand 40 may include a fixed base having a shape of a rectangular
plate (a paperweight structure), but this is not limitative.
Alternatively, the stand 40 may have a tilt-swivel mechanism
capable of changing vertical and horizontal orientations of a
screen of the display panel 10.
[0042] In the display device 1, light emitted from the light source
17A is incident on the display panel 10 through the light guide
plate 17 and the optical sheet 16. The incident light passes
through the polarization plate 15B, and permeates the liquid
crystal layer 13 while being modulated for each pixel based on a
picture voltage applied between the transparent electrodes on the
TFT substrate 12 and the CF substrate 14. The light that permeates
the liquid crystal layer 13 permeates the color filter to be
extracted as color display light externally of the polarization
plate 15A (on the display surface side).
[0043] FIG. 7 illustrates a cross-sectional configuration of a
general display device 100. The display device 100 has a
configuration in which, similarly to the display device 1 according
to the above-described example embodiment, an optical sheet 116, a
light guide plate 117, a reflection plate 118, and a backlight unit
19 are accommodated in a back surface member 131 and a support
member 132 that constitute a casing 130. The display panel 110 is
adhered to a frame section 132A of a support member 132. In the
display device 100, the casing 130 is configured of, in addition to
the back surface member 131 and the support member 132, a front
surface member 133 in a frame shape that covers an outer edge of
the display panel 110 from the front surface. The front surface
member 133 is formed of a metal such as Al or Fe, or the like,
similarly to the back surface member 131 and the support member
132. Accordingly, in the display device 100, the number of
components is increased, which puts more weight.
[0044] Moreover, a frame region Si of the display device 100
constitutes a frame section 133A of the front surface member 133.
The frame section 133A holds the display panel 110 between the
frame section 133A and the support member 132. Accordingly, the
front surface member 133 involves an overlap region that overlaps
the outer edge of the display panel 110 and a screw fixing region
that fixes the front surface member 133 to the back surface member
131 or the support member 132. That is, the display device 100
involves the frame region Si of a certain extent, and moreover, a
display region S2 of the display panel 110 is narrowed because the
outer edge of the display panel 110 is covered with the front
surface member 133.
[0045] On the other hand, in the display device 1 according to the
present embodiment, the sealing resin layer 20 is provided on the
peripheral edge of the display panel 10 (or 10A), and the surface
on the display side of the sealing resin layer 20 is molded to form
the same plane as the surface of the display panel 10 (or 10A).
Thus, a configuration of structural members is simplified.
Specifically, the front surface member 133 of the casing 130 in the
general display device 100 is eliminated.
[0046] As described above, in the display device 1 according to the
present embodiment, the sealing resin layer 20 is provided and
molded on the peripheral edge of the display panel 10 (10A). The
sealing resin layer 20 includes the same plane as the surface of
the display panel 10. This contributes to a simplified
configuration of structural members. Hence, it is possible to
reduce cost and to reduce weight of the display device 1.
[0047] Moreover, specifically, the level difference in the end
surface of the display panel 10A, which is caused by a combination
of structural members of different sizes, is embedded in the
sealing resin layer 20, allowing the end surface to be planarized.
Hence, it is possible to use the display panel 10A as a front
surface member as it is. In other words, the front surface member
133 in the display device 100 becomes unnecessary. The front
surface member 133 holds the display panel 110 between the front
surface member 133 and the support member 132 or the like and
covers the outer edge of the display panel 110, including the end
surface. Hence, flexibility of design in the vicinity of the
display surface is improved, enhancing designability of appearance
of the display device 1.
[0048] Further, the front surface member including the screw fixing
region and so on is eliminated, allowing the sealing resin layer 20
to form a frame of the display panel 10 without fixing with screw.
Hence, it is possible to narrow a frame of the display device 1.
Furthermore, since the overlap region between the front surface
member 133 and the display panel 110 is eliminated, an effective
pixel region of the display panel 10 is broadened in the display
device 1.
[0049] Moreover, in the present embodiment, the lamination film 21
is attached to the entire display surface of the display panel 10A
and the sealing resin layer 20 for exterior finish. However, the
sealing resin layer 20 may be colored in black or the like, making
it possible to use the surface of the display panel 10A and the
surface of the sealing resin layer 20 for exterior finish as it is.
Moreover, since a colored layer is provided on the peripheral edge
of the display panel 10A, light leakage or the like from the side
surface is reduced, making it possible to enhance display
characteristics of the display device 1.
[0050] In the following, description will be given on one
modification example and one application example related to the
above-described example embodiment. It is to be noted that similar
components to the above-described example embodiment will be
denoted by similar reference numerals, and description thereof will
be omitted.
2. Modification Example
[0051] FIG. 4 illustrates a cross-sectional configuration of a main
part (a display panel 10B and its periphery) of a display device 2
according to one modification example of the example embodiment of
the present disclosure. In the present modification example, the
display panel 10B is configured of the cell 11 that includes the
liquid crystal layer 13 between the TFT substrate 12 and the CF
substrate 14, and has a configuration in which the sealing resin
layer 20 is provided on the peripheral edge of the display panel
10B (the cell 11). In the present modification example, the surface
on the display side of the sealing resin layer 20 forms the same
plane as the surface of the CF substrate 14 of the cell 11, and on
the plane S1, the polarization plate 15A is provided. A difference
from the above-described example embodiment is in that the
polarization plate 15A is extended to an end surface of the sealing
resin layer 20.
[0052] As mentioned above, in the display device 2 according to the
modification example, the sealing resin layer 20 is formed on the
peripheral edge of the display panel 10B, forming the same plane as
the CF substrate 14 that constitutes the display panel 10B. Thus,
similarly to the above-described example embodiment, provision of
the front surface member may be eliminated. In other words, a
configuration of structural members is simplified, leading to
weight reduction. It is also possible to enhance designability of
appearance.
[0053] Further, since the front surface member is eliminated, it is
possible to achieve narrowing of a frame. Furthermore, to the plane
Si that is formed by the CF substrate 14 and the sealing resin
layer 20, attached is the polarization plate 15A, which is extended
to the end surface of the sealing resin layer 20. Hence, it is
possible to use the polarization plate 15A for exterior finish as
it is, leading to a further cost reduction.
3. Application Example
[0054] The display devices 1 and 2 as described in the
above-mentioned example embodiment and the modification example may
be suitably used in an electronic apparatus 3 (a television set) as
illustrated in FIG. 5. FIG. 6 illustrates a cross-sectional
configuration along a line I-I (the display panel 10 and a
peripheral member 50) of the television set as illustrated in FIG.
5. The television set may have a configuration in which, for
example, the peripheral member 50 is mounted to each of both sides
of the display device 1. The peripheral member 50 may include, for
example, a speaker 51 and a metal plate 52. In this way, in the
display devices 1 and 2 according to the example embodiment and so
forth of the present embodiment, it is possible to use the sealing
resin layer 20 as a connection member between the display panel 10
and the peripheral member 50.
[0055] Although description has been made by giving the example
embodiment and the modification example as mentioned above, the
contents of the present technology are not limited to the
above-mentioned example embodiment and so forth, and may be
modified in a variety of ways. For example, in the above-described
example embodiment and so forth, the display devices 1 and 2 have
been exemplified by a liquid crystal display device. However,
examples of possible applications may include a plasma display
device or an organic electroluminescence display device.
[0056] Moreover, each structural member as described in the
above-mentioned example embodiment and so forth is merely
exemplary. It is not necessary to include all the structural
members, and another structural member or other structural members
may be further provided. For example, as a heat dissipation
mechanism of heat produced from the light source 17A, a heat sink
may be attached to at least part of the back surface of the display
device, for example, a lower end portion where the light source 17A
is disposed. For the heat sink, a metal having high thermal
conductivity may be desirably used. For example, a mold of a block
of aluminum (Al) or the like may be used.
[0057] It is to be noted that effects described in the
specification are merely exemplified and not limitative, and
effects of the present disclosure may be other effects or may
